A study, aimed at determining if adding porous particles, tricalcium phosphate/hydroxylapatite or defatted morsellized cancellous allograft bone (MCB), to hydroxylapatite cement (HAC) could improve its incorporation without compromising strength, was presented. Bilateral cancellous bone defects were drilled from the lateral direction in the distal femora of 24 rabbits. Using indentation tests, it was found that both HAC/bone sensitive granules (BSG) and HAC/MCB were stronger than intact cancellous bone initially and after eight weeks in vivo (<0.05). THe HAC groups were also found to be stronger than the empty defects and MCB groups at eight weeks (P<0.05).
